I've had this problem show up twice in the last five or six times I started the bike. Hit the starter and the bike doesn't fire right away, just keeps turning over. Add throttle and it starts but need to keep throttle partly open for about 5-10 seconds with light revving, then the idle settles down and idles properly. No rpm variations like the stepper motor problem. This has happened once when the engine was cold and once when the engine was warm after a stop for a bathroom break. Is this the spark plug cap arcing problem or is there something else that needs to be addressed? Prior to this, the engine always started normally when I pressed the button (except for when I had the "startus interruptus" problem which I solved with the wiring fix described here in the Ghetto).
